[SF][A11y][DatePicker] Pressing Enter key won't select the date

[Neeeko]

Bug Description

When using the keyboard to navigate in the DatePicker, pressing the ENTER key will only close the DatePicker instead of selecting the date and displaying it in the DatePicker input.
However, it works well using SPACE key.

In the documentation it is indicated that
Once the drop-down is opened, you can use the UP, DOWN, LEFT, RIGHT arrow keys to navigate through the dates and select one by pressing the Space or Enter keys

Expected Behavior

Pressing ENTER key on a date should select the date properly, close the DatePicker and display the selected date in the DatePicker input.

Steps to Reproduce

1. Go to https://sap.github.io/ui5-webcomponents/playground/components/DatePicker/
2. Open the Datepicker using the Keyboard and navigate to a date
3. Press ENTER key
4. The selected Date won't be displayed in the Date Picker input
